摘要： A method for maintaining a cache of dynamically generated objects. The method includes storing in the cache dynamically generated objects previously served from an originating server to a client. A communication between the client and server is intercepted by the cache. The cache parses the communication to identify an object determinant and to determine whether the object determinant indicates whether a change has occurred or will occur in an object at the originating server. The cache marks the object stored in the cache as invalid if the object determinant so indicates. If the object has been marked as invalid, the cache retrieves the object from the originating server.

摘要： The present invention is directed towards a method and system for providing a technique referred to as flash caching to respond to requests for an object, such as a dynamically generated object, from multiple clients. This technique of the present invention uses a dynamically generated object stored in a buffer for transmission to a client, for example in response to a request from the client, to also respond to additional requests for the dynamically generated object from other clients while the object is stored in the buffer. Using this technique, the present invention is able to increase cache hit rates for extremely fast changing dynamically generated objects that may not otherwise be cacheable.

摘要： The present invention is directed towards a method and system for modifying by a cache responses from a server that do not identify a dynamically generated object as cacheable to identify the dynamically generated object to a client as cacheable in the response. In some embodiments, such as an embodiment handling HTTP requests and responses for objects, the techniques of the present invention insert an entity tag, or “etag” into the response to provide cache control for objects provided without entity tags and/or cache control information from an originating server. This technique of the present invention provides an increase in cache hit rates by inserting information, such as entity tag and cache control information for an object, in a response to a client to enable the cache to check for a hit in a subsequent request.

摘要： The present invention is directed towards a “flash crowd” technique for handling situations where the cache receives additional requests, e.g., nearly simultaneous requests, for the same object during the time the server is processing and returning the response object for a first requestor. Once all such nearly simultaneous requests are responded to by the cache, the object is flushed from the cache, with no additional expiry time or invalidation action needed. This technique of the present invention enables data to be cached and served for very small amounts of time for objects that would otherwise be considered non-cacheable. As such, this technique yields a significant improvement in applications that serve fast changing data to a large volume of concurrent users, such, for example, as real time stock quotes, or a fast evolving news story.

摘要： The present invention is directed towards a method and system for providing granular timed invalidation of dynamically generated objects stored in a cache. The techniques of the present invention incorporates the ability to configure the expiration time of objects stored by the cache to fine granular time intervals, such as the granularity of time intervals provided by a packet processing timer of a packet processing engine. As such, the present invention can cache objects with expiry times down to very small intervals of time. This characteristic is referred to as “invalidation granularity.” By providing this fine granularity in expiry time, the cache of the present invention can cache and serve objects that frequently change, sometimes even many times within a second. One technique is to leverage the packet processing timers used by the device of the present invention that are able operate at time increments on the order of milliseconds to permit invalidation or expiry granularity down to 10 ms or less.
